This final volume of a six-volume study of an elementary school called "Kensington" in a school district code-named "Milford," examines its own assumptions and procedures. After the brief, introductory chapter, which presents the methodological appendixes of the preceding volumes as a serial, chapter 2 discusses exploratory and final proposals for the study and its followup relation to an early study ("Middletown in Transition"). Chapter 3, "Ethnography as an Intellectual Process," examines the study's evolving logic; accidents, anomalies, and serendipity; the observer's role; and archival case records. Chapter 4 expands the third chapter's focus on ethnography to include separate sections on "Ethnography,""Ethnography and Historical Method," and "Educational Innovation and Life History." This final volume concludes with a chapter on "Paradigms in Debate." In order to protect the anonymity of the school district studied in such detail, pseudonyms have been used for all place names (school, school district, city, county, state) and personal names (school superintendents, school board members, teachers, students) appearing in the various volumes of this set.
